Trivia: In what year did a motorcyclist first break 100 mph?

Answer: B: on anExcelsior built in Chicago ridden by Lee Humiston "On December 30th, 1912, Humiston circled the banked one-mile oval on his direct-drive Excelsior in 36 seconds flat, to become the first motorcyclist in the world 'officially' timed at 100 mph." Source: www.statnekov.com/

It should be noted that while this is the official first time someone broke 100mph, Glenn Curtiss unofficially broke the record in 1907. Since the officials who record such events weren't among the witnesses, his 138mph is not officially recognized as the record at that time.
